hello again it's me paxi
today let's go and explore the moon now
tell me do you think the moon was always
there
let's go back in time four and a half
billion years and find out
most scientists believe that the moon
was born when a young planet crashed
into the earth
it was a big crash
huge amounts of material were thrown
into space and later came together to
form the moon
earth was a very different place back
then let's now go back to 1969
when the first man neil armstrong
stepped on the moon
it was a really special moment
millions of people on earth watched it
live on tv
your grandparents probably remember
humans returned to the moon's surface
five more times they investigated and
collected hundreds of kilograms of moon
rocks and brought them back to earth
when scientists examined these rocks
they discovered that they are like
earth's rocks that's why they thought
the moon was also formed out of
materials coming from earth during that
early crash
but the last time humans went to the
moon was in 1972
since then only man-made machines
satellites and robots have visited the
moon
there have been many of them the good
news is that today scientists and
engineers are preparing to send back
astronauts to the moon and stay for a
long time
look at all the experiments they are
doing
come with me to the moon to see what
they need to prepare for future
exploration
wow look back at the beautiful blue
earth
living on the moon would be very
different from earth when it is dark on
the moon it can get colder than anywhere
on earth but when the sun shines it gets
hotter than boiling water i'd better go
inside my spaceship ah
that is much better in here i am
protected from these extreme
temperatures and from the sun's
radiation
to stay on the moon i need somewhere to
live kind of like when you go camping on
earth you have to build a shelter
but a moon shelter would need to be more
high-tech to protect from the
temperatures and radiation of space
maybe i could build one out of the lunar
soil
or i could dig a tunnel underground
or i could even inflate one like a
balloon
i also need electricity but there is no
oil or coal to burn or wind power to use
that leaves the sun
[Music]
i could use solar power on the moon just
like the houses on earth that have solar
panels on the roof
hmm
i am more comfortable now
but i am thirsty where could i get water
did you know there is water ice on the
moon but only at the poles in cold
craters where the sun never shines come
with me to a lunar pole and drill to get
some
water is very important we need it to
drink
i could also produce oxygen from it and
that is really important because the
moon does not have an atmosphere so
there is no air to breathe i could even
use water to produce few water launch
rockets
[Music]
but i am also hungry
there is no food here
on earth i can grow fruit and vegetables
maybe i can do the same on the moon
i would need to build my own greenhouse
and take good care of my plants
look at that potatoes are growing
now i have shelter power
water air and food
that is all i need to stay on the moon
for a long time
so
today we learned that the moon was
probably formed when a young planet
crashed into the earth billions of years
ago
astronauts have landed on the surface of
the moon six times
currently only satellites and robots
study the moon
humans are preparing to go back to the
moon
to live on the moon we would need
shelter
power
water
air
and food
